2012 MAR 9 -- "This study investigated the hypothesis that adaptations would occur in the sarcoplasmic reticulum in vastus lateralis soon after the onset of aerobic-based training consistent with reduced Ca2+-cycling potential. Tissue samples were extracted prior to (0 days) and following 3 and 6 days of cycling performed for 2 h at 60%-65% of peak aerobic power (VO2peak) in untrained males (VO2peak = 47 +/- 2.3 mL. kg(-1). min(-1); mean +/- SE, n = 6) and assessed for changes (nmol. mg protein(-1). min(-1)) in maximal Ca2+-ATPase activity (V-max), Ca2+-uptake, and Ca2+-release (phase 1 and phase 2) as well as the sarcoplasmic (endoplasmic) reticulum Ca2+-ATPase (SERCA)...
